Thanks for your advice, Andy. From the documentation I have been able to
find on badmailfrom I am unable to determine if it will block an entire host
or just certain senders addresses. I think in my case I need to block any
mail that originates from a specific host. Otherwise, tomorrow the SPAMers
may just decide to change the bogus MAIL FROM: address they are using. Can
you clear this up? Or point me in the right direction?
Thanks,
Aaron

Without some hacking you won't be able to block based on the From:
header, however you can block based on the sender envelope. See the
man page for qmail-smtpd which specifically references the use of the
badmailfrom control file.
